Abstract

A multifunctional and dual-purpose safety lamp base comprises a large spring, a small spring, a large contact, an insulation wall, an insulation lap, a touch column, a copper cap and a small contact. A terminal strip has a cassette structure and the two cassettes take the shape of an inverted tooth. A jack screw copper circle consists of a jack and a thread with the jack on the above and the jack diameter shorter than that of the thread and two symmetrical inverted L-shaped jack slots on the thread. The utility model integrates the jack and the thread, thus making the use of both a screw bulb and a thread bulb possible in one lamp base and bringing great convenience to the users. By adopting the cassette structure, not only does the terminal strip become reliable and safe, but also time-conscious and convenient for the assembling, saving conduit and reducing the production costs. Having a small horn shape, the shell of the utility model is longer than that of the original and the metal part of light bulbs does not expose to the outside and leakage not happen. The horn shape matches with the shape of the bulbs, generating beautiful appearance and safety.

Description

Multifunctional safe dual-purpose lamp socket

Technical field

The utility model is a kind of lamp socket, particularly to the improvement of holder structure.

Background technology

The syndeton of existing civilian lamp socket and bulb has two kinds, and is a kind of for being threaded, and a kind of is that socket connects.Both can not exchange general, make troubles to use.No. 93226357.7 patent disclosures of ZL a kind of safety lamp holder, its structure is by housing, lamp ring, lug plate, strikes the post and form, strike the post include greatly strike the post, strike the post for a short time, big spring, little spring, strike the post greatly is that a centre is the cylinder of cavity, in little spring, an end of striking the post for a short time place and strike the post greatly, and make large and small striking the post be linked as a mobilizable integral body with capping, the other end of striking the post for a short time is with big spring, strike the post greatly and place in the seat of striking the post, for a short time strike the post and lug plate directly is provided with an insulating trip, and can contact or disconnect with lug plate by the aperture on the insulating trip.The lamp socket of this structure is connected with bulb by the screw socket on the lamp ring.Because housing is shorter, after screw socket and bulb screwed, the threaded portion of bulb also had one section to be exposed, if after the energising, this part that expose very easily causes electric leakage, uses still very dangerous.The lug plate of this lamp socket is by the screw lead, and after screw-socket bulb screwed in, the bending of lug plate easy deformation can cause short circuit; But also need long section lead on screw, because screw screws, lead can be intertwined and cause lead to fix, and uses very inconvenient sometimes.

Summary of the invention

The utility model provides a kind of multifunctional safe dual-purpose lamp socket that has improved.Structure includes big spring 2, little spring 3, big contact 4, socket rib collar copper band 5, bakelite spare shell 6, electricity-isolation wall 7, insulated ring 8, strike the post 9, copper lid 10, small contact 11, and lug plate 1 is the cassette structure, and two cards are the formula of setting one's teeth on edge.

Socket rib collar copper band 5 can be made up of socket and rib-loop two parts, and jack part is positioned at the top, and the diameter of jack part is less than the diameter of rib-loop part, and symmetry has two and falls L shaped socket groove 12 on the rib-loop part.

Bakelite spare shell 6 length are greater than the length of existing common outer cover of lamp holder, and it is shaped as toy trumpet shape.So in use, the length of shell can cover in the metal part of bulb fully, is unlikely to take place leaky; And the profile of bulb is just in time coincide with the toy trumpet shape of this lamp socket.

The utility model is integrated screw socket and outlet structure.When using as plug adapter, two pin on the socket bulb insert in the socket groove and get final product, and have realized can using screw-socket bulb and socket bulb respectively on a lamp socket, and the use of bulb no longer is restricted, and bring great convenience to use.Lug plate adopts the cassette structure, and is not only safe and reliable as long as insert lead, and assembling is extremely easy, saves time, and has saved lead, has reduced production cost.Shell of the present utility model is longer than original shell, and becomes the toy trumpet shape, and after bulb screwed on, the metal of bulb part can not be exposed again, just leaky can not take place again yet like this; And its toy trumpet shape just in time matches with the profile of bulb, and is both attractive in appearance, again safety.

Accompanying drawing is the utility model domestic type structural representation.

1 lug plate, 2 big springs, 3 little springs, 4 big contacts, 5 socket rib collar copper bands, 6 bakelite spare shells, 7 electricity-isolation walls, 8 insulated rings, 9 are struck the post, 10 bronze medals lid, 11 small contacts, 12 socket grooves.

Embodiment

Multifunctional safe dual-purpose lamp socket includes big spring 2, little spring 3, big contact 4, socket rib collar copper band 5, bakelite spare shell 6, electricity-isolation wall 7, insulated ring 8, strikes the post 9, copper lid 10, small contact 11, and lug plate 1 is the cassette structure, and two cards are the formula of setting one's teeth on edge.Socket rib collar copper band 5 is made up of socket and rib-loop two parts, and jack part is positioned at the top, and the diameter of jack part is less than the diameter of rib-loop part, and symmetry has two and falls L shaped socket groove 12 on the rib-loop part.Bakelite spare shell 6 length are greater than the length of existing common outer cover of lamp holder, and it is shaped as toy trumpet shape.

Claims (3)

1, a kind of multifunctional safe dual-purpose lamp socket, include bakelite spare shell (6), big spring (2), little spring (3), big contact (4), socket rib collar copper band (5), electricity-isolation wall (7), insulated ring (8), strike the post (9), copper lid (10), small contact (11), it is characterized in that lug plate (1) is the cassette structure, two cards are the formula of setting one's teeth on edge.

2, according to the described multifunctional safe dual-purpose of claim 1 lamp socket, it is characterized in that socket rib collar copper band (5) is made up of socket and rib-loop two parts, jack part is positioned at the top, the diameter of jack part is less than the diameter of rib-loop part, and symmetry has two and falls L shaped socket groove (12) on the rib-loop part.
